CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts that form the backbone of your Web3 product. Our development process ensures security-first code, gas optimization, and regulatory compliance from day one.

  • Audit-Ready Code: Built with Solidity 0.8+ using OpenZeppelin libraries and battle-tested patterns.
  • Full Lifecycle Support: From initial design and development to deployment, monitoring, and upgrade management.
  • Key Deliverables: Token contracts (ERC-20, ERC-721, ERC-1155), DeFi primitives, governance systems, and custom business logic.

Reduce your time-to-market from months to weeks with our templatized yet customizable approach.

We focus on delivering measurable outcomes:

  • 99.9% uptime for contract availability post-launch.
  • 30-50% gas cost reduction through optimization audits.
  • Zero critical vulnerabilities in production deployments, verified by third-party audits from firms like CertiK and Quantstamp.

ENTERPRISE-GRADE SECURITY

Core Privacy Capabilities We Implement

We architect privacy directly into your media NFT platform, ensuring creator control, regulatory compliance, and user trust without sacrificing performance.

01

Zero-Knowledge Proofs for Asset Privacy

Implement ZK-SNARKs and ZK-STARKs to enable private ownership verification and selective disclosure of NFT metadata. Creators can prove provenance without revealing sensitive data, and collectors can verify authenticity privately.

EXPLORE
02

Confidential Transaction Layers

Deploy layer-2 solutions like Aztec or zkRollups to shield transaction amounts and participant identities on-chain. Enables private bidding, sales, and royalty distributions for high-value media assets.

EXPLORE
03

Encrypted Metadata & Content Storage

Integrate decentralized storage (IPFS, Arweave) with client-side encryption. Media files and unlockable content remain encrypted, accessible only to verified NFT holders via secure key management.

EXPLORE
04

Access Control & Token-Gated Experiences

Build dynamic, on-chain access rules using ERC-1155 or Soulbound Tokens (SBTs). Create private galleries, exclusive content drops, and membership tiers with revocable, privacy-preserving permissions.

EXPLORE
05

Regulatory-Compliant Privacy (MiCA, GDPR)

Design privacy architectures that facilitate compliance. Implement data minimization, right-to-erasure workflows, and audit trails for regulators while maintaining user pseudonymity on-chain.

06

Stealth Address & Mixer Integration

Integrate privacy primitives like stealth address generation and trusted mixer protocols to break the on-chain link between a user's public identity and their NFT transactions.

Business Outcomes for Media Platforms

We deliver production-ready infrastructure for privacy-preserving media NFT transactions, enabling new revenue streams and audience engagement without compromising user data.

01

Zero-Knowledge Proof Integration

Implement zk-SNARKs or zk-STARKs to enable private ownership verification and royalty distribution. Media platforms can prove transaction validity without revealing sensitive viewer or creator data on-chain.

Privacy-Preserving Media NFT Transactions

Frequently Asked Questions

Get clear answers on how we build secure, private NFT marketplaces for sensitive media. Based on 50+ successful Web3 deployments.

A production-ready, privacy-preserving NFT platform for media typically deploys in 4-8 weeks. This includes a 2-week discovery/design phase, 3-5 weeks of core development, and 1 week for final testing and deployment. Complex integrations (e.g., custom on-chain/off-chain data flows) can extend this timeline, which we scope during the initial technical assessment.
